What do you mean "Ez controller-Orders" ? What software you are talking about?
On Noritsu QSS3701HD can be installed EZ controller + minilab system software + scanner system software ( if your minilab has scanner ) + profiles + optional EZ controller modules.
Any Ez controller version can be used on your minilab. Version 5.8 can be installed on Windows 7 and version 6.6 - on Windows 10. Time is going and version 6.6 is already outdated.
Pay attention - if to use Windows 10 also need new printer and scanner system software. If need more information - write private message. There can explain how to install all and transfer from old system.
